Description

Audio transmission line and headphones

The present invention relates to a sound source transmission line and an earphone, and more particularly to a sound source transmission line and an earphone for a transmission sequence of a switchable feed signal.

In general, when a user wants to listen to an audio signal in an electronic device (such as a mobile phone, an MP3 player, a PDA, etc.), in addition to directly playing the sound on the electronic device, the sound source of the earphone can also be selected for transmission. The connector is plugged into the earphone socket of the electronic device such that the speaker on the earphone can play an audio signal in the electronic device. With the evolution of technology, the audio transmission connectors of the headphones on the market can be generally divided into three sections and four sections, each of which is a signal transmission unit. At present, four signal coupling ends are generally provided in the earphone socket of the electronic device to correspond to the four-section audio source transmission connector, so that each signal transmission unit can carry different earphone signals. Here, the earphone signals carried by the signal transmission units may be a left channel signal, a right channel signal, a microphone signal, and a ground signal, respectively.

If the mobile phone is taken as an example, although the mobile phone manufacturers have unified specifications for the size and size of the earphone socket, the definitions of the four signal coupling terminals in the earphone socket are different for each mobile phone manufacturer. For example, some mobile phone manufacturers are accustomed to transmitting the left channel signal with the first signal coupling end of the earphone socket (corresponding to the first signal transmission unit on the audio source transmission connector of the earphone), but there is another part of the mobile phone. The manufacturer is accustomed to transmitting the microphone signal by the first signal coupling end of the earphone socket (corresponding to the first signal transmission unit on the audio source transmission connector of the earphone).

That is to say, the transmission order of the earphone signals by the mobile phone manufacturers is not necessarily the same, but since the circuit inside the conventional earphone is fixed, if the first signal transmission unit is preset to be connected to the speaker element of the left ear, obviously The speaker element of the left ear can only correctly interpret the left channel signal, and there is no way to process the microphone signal. On the other hand, if the first signal transmission unit has been preset to be connected to the microphone element, the microphone element can only correctly interpret the microphone signal, and there is no way to process the left channel signal.

In order to solve the problem that the transmission order of the above-mentioned earphone signals is not necessarily the same, the Republic of China invention patent No. I324891 discloses an earphone which can adaptively interpret a plurality of earphone signals, and the main contents of the previous case are shown in FIG. As can be seen from FIG. 1, the earphone device 9 of the No. I324891 has a sound source transmission connector 90 and a plurality of sets of switches SW1 SWSW4, and the signal transmission unit 902 is correspondingly connected to the switch SW1. Similarly, the signal transmission units 904-908 are also connected one-to-one. Switch SW2~SW4. In addition, the sound source transmission connector 90 can receive the left channel signal, the right channel signal, the microphone signal, and the ground signal from the mobile phone through the signal transmission units 902-908.

Here, the Patent No. I324891 claims that the left channel signal, the right channel signal, the microphone signal, and the ground signal of the mobile phone do not necessarily appear in which signal transmission unit (depending on the specifications of each mobile phone manufacturer). Therefore, the earphone device 9 is actually configured with 16 modes of signal transmission. Taking the switch SW1 as an example, the switch SW1 can arbitrarily output the headphone signal carried by the signal transmission unit 902 into a left channel signal LCH, a right channel signal RCH, a microphone signal MIC or a ground signal GND that can be received by the earphone. That is to say, the patent No. I324891 can solve the transmission sequence of the headphone signal when the four switches can output the left channel signal LCH, the right channel signal RCH, the microphone signal MIC or the ground signal GND which can be received by the earphone. Not necessarily the same problem.

However, from the point of view of actual use and manufacturing, switching of 16 kinds of signal lines is achieved only through mechanical and structural operations, so that the four switches respectively output the headphones in the manner of the patent No. I324891 (especially the third figure). The four types of signals that can be received (LCH, RCH, GND, MIC) are obviously impossible to implement. From the description of page 9 of the specification of the No. I324891 patent, the patent No. I324891 requires an additional control signal generator to generate a control signal, and uses the control signal to switch the signal transmission modes of the four switches. In other words, the patent No. I324891 actually uses an IC chip to control the four switches to select 16 signal transmission modes.

It should be understood by those having ordinary knowledge in the technical field that it is not easy for a user to select the correct signal transmission mode from among 16 signal transmission modes (in particular, the user does not necessarily understand the difference in the transmission order of the headphone signals). If the IC chip is placed in the earphone, the production and manufacturing cost of the earphone will be greatly increased, and additional batteries or power lines need to be installed and configured to provide the power required for the IC chip, which will make the earphone product uncompetitive.

It is worth mentioning that China's publication No. 201143226 discloses an earphone that achieves a switching signal line through mechanical and structural operations. However, it can be seen from the pages 11-14 of the specification of the publication No. 201143226, the publication No. 201143226 merely discloses the technique of switching the three-section and four-section audio source transmission joints, and actually there is no way to solve the above-mentioned earphone signal. The transmission order is not necessarily the same, and since the structure disclosed in the publication No. 201143226 is too simple, there is no way for a person having ordinary knowledge in the technical field to use the combination of the publication No. I324891 and No. 201143226 Achieve more complex switching functions.

Therefore, how to solve the problem that the transmission order of the above-mentioned earphone signals is not necessarily the same without using an IC chip is an object that the industry is currently trying to achieve.

The embodiment of the invention provides a sound source transmission line, which can mechanically switch the electrical connection relationship of the physical line, so that the earphone signal transmitted by the sound source transmission connector can be correctly received by the earphone. Therefore, the present invention can solve the problem that the transmission order of the headphone signals by different manufacturers is not necessarily the same in the case where the IC chip is not required to be used.

The embodiment of the invention provides a sound source transmission line, and the sound source transmission line has a sound source transmission joint and a wire controller. The audio source transmission connector has a plurality of signal transmission units for transmitting a plurality of earphone signals of the electronic device. The wire controller is coupled to the sound source transmission connector via the signal cable, and the wire controller has a signal input module, a signal output module, a first control component, and a complex array wire circuit. The signal input module has a plurality of signal input terminals, and each of the signal input terminals is coupled to one of the plurality of signal transmission units one-to-one.

The first control member mechanically couples at least the first conductive member and the second conductive member, the input end of the first conductive member is coupled to the plurality of signal input ends, and the output end of the second conductive member is coupled to the plurality of Signal output. There is a preset terminal correspondence between the input end and the output end of each set of wire circuits, and different wire circuits are different in the corresponding terminal correspondence relationship. In addition, the first control member selectively controls the output end of the first conductive member to be coupled to the input end of one of the plurality of sets of wire circuits, or to control the input end of the second conductive member to be coupled to the same set of wire circuits Output.

In an exemplary embodiment of the invention, the wire controller has a first body portion and a second body portion, the first body portion is for receiving the first switch, and the second body portion is rotatably coupled to the first body portion. When the second body portion is rotated relative to the first body portion, the second body portion is coupled to the first control member, so that the first control member controls the first conductive member and the second conductive member to simultaneously couple one of the plurality of sets of wire circuits group.

In addition, an embodiment of the present invention provides an earphone that can mechanically switch an electrical connection relationship of a physical line so that a headphone signal transmitted by the sound source transmission connector can be correctly received by the earphone. Therefore, the present invention can solve the problem that the transmission order of the headphone signals by different manufacturers is not necessarily the same in the case where the IC chip is not required to be used.

The first control member mechanically interlocks the first conductive member and the second conductive member, the input end of the first conductive member is coupled to the plurality of signal input ends, and the output end of the second conductive member is coupled to the plurality of signals Output. The first switch has a complex array of wire circuits, and a predetermined terminal correspondence relationship between the input end and the output end of each set of wire circuits, and different wire circuits are different in the corresponding terminal correspondence relationship. In addition, the first control member selectively controls the output end of the first conductive member to be coupled to the input end of one of the plurality of sets of wire circuits, and simultaneously controls the input end of the second conductive member to be coupled to the same set of wire circuits The output. The sound output device is coupled to the signal output module, and correspondingly generates sound according to the sequence of the earphone signals output by the plurality of signal output ends.

Thereby, the user can mechanically switch different wire circuits through the control device according to the specifications of different electronic devices, so that the earphone signal transmitted by the sound source transmission connector can be correctly received by the earphone.

For a better understanding of the features and technical aspects of the present invention, reference should be made to the accompanying drawings.

[An exemplary embodiment of the earphone of the present invention]

Referring to FIG. 2A, FIG. 2A is a schematic circuit diagram of an earphone coupled to a set of lead circuits according to an embodiment of the invention. As shown in FIG. 2A, the earphone 1 of the present invention has a sound source transmission joint 10, a wire controller 12, and a sound output device 14. In practice, the sound source transmission connector 10 is connected to the wire controller 12 via a signal cable (not shown in FIG. 2A), and the sound output device 14 can be a speaker and a microphone that are commonly found in commercially available earphones. Here, the sound source transmission connector 10 and the wire controller 12 can be combined to be regarded as one sound source transmission line, and the sound output device 14 can be fixedly or pluggably connected to the signal output module of the sound source transmission line. The relative relationship and function of each component in the earphone 1 will be separately described below.

The sound source transmission connector 10 has a signal transmission unit 102, a signal transmission unit 104, a signal transmission unit 106, and a signal transmission unit 108 for transmitting a type of earphone signal, respectively. In practice, the audio source transmission connector 10 is plugged into an electronic device (not shown), and the earphone signal includes a left channel signal, a right channel signal, a microphone signal, and a ground signal. Since the electronic device does not fix the output order of the left channel signal, the right channel signal, the microphone signal, and the ground signal, the present invention does not limit the type of the headphone signal carried by any one of the signal transmission units (102 to 108). In addition, the present invention also does not limit the size of the sound source transmission connector 10. For example, the sound source transmission connector 10 can be used for plugging into a 2.5 mm or 3.5 mm earphone hole, which can be designed by a person having ordinary knowledge in the art. .

In the embodiment, the line controller 12 has a signal input module 120, a signal output module 122, a switch 124, and a control unit 126. The signal input module 120 has a plurality of signal input terminals (120a-120d), and each of the signal input terminals is coupled to one of the plurality of signal transmission units (102-108) one-to-one. For convenience of description, the present embodiment demonstrates coupling the signal input end 120a to the signal transmission unit 102, the signal input end 120b is coupled to the signal transmission unit 104, and the signal input end 120c is coupled to the signal transmission unit 106, and the signal input end. 120d is coupled to signal transmission unit 108, however such electrical connection relationship is not intended to limit the invention. For example, the signal input terminal 120a can of course be coupled to other signal transmission units. Without a signal input unit coupled to a signal input unit, a person skilled in the art can freely change the signal input. The coupling relationship between the terminal and the signal transmission unit.

The signal output module 122 has a plurality of signal outputs (122a-122d) such that the headphone signals can be transmitted between the sound output device 14 and the line controller 12. In practice, the sound output device 14 may have terminals such as a left speaker transmission end, a right speaker transmission end, a ground end, and a microphone transmission end. For example, the present invention can couple the signal output end 122a to the left speaker transmission end, the signal output end 122b to the right speaker transmission end, the signal output end 122c to the ground end, and the signal output end 122d to the signal output end 122d. Connected to the microphone transmission end. In other words, as long as the signal output terminal 122a correctly receives the left channel signal, the signal output terminal 122b correctly receives the right channel signal, the signal output terminal 122c correctly receives the ground signal, and the signal output terminal 122d correctly receives the microphone signal. The sound output device 14 can work normally.

The switch 124 has a complex array of conductor circuits (1240~1244). There is a preset terminal correspondence between the input end and the output end of each set of lead circuits, and the corresponding relationship of the different lead circuits is different. In addition, the control member 126 mechanically interconnects the conductive member 1260 and the conductive member 1262, whereby the control member 126 can selectively control the conductive member 1260 and the conductive member 1262 to be respectively coupled to the plurality of sets of lead circuits (1240~1244). One of the two ends. For example, FIG. 2A illustrates an example in which the user directly manipulates the control member 126 and couples the conductive member 1260 and the conductive member 1262 to the ends of the wire circuit 1240, respectively.

In practice, the conductive member 1260 can have a set of input terminals 1260a and a set of output terminals 1260b. The input terminal 1260a and the output terminal 1260b can each have four independent conductive points, and the first to fourth conductive points of the input terminal 1260a are respectively It is electrically connected to the first to fourth conductive points of the output terminal 1260b. In addition, the four conductive points of the input end 1260a of the conductive member 1260 are respectively coupled to the signal input ends (120a-120d), and the four conductive points of the output end 1262b of the conductive member 1262 are respectively coupled to the signal output ends (122a-122d). . Please note that the coupling relationship between the conductive member 1260 and the signal input module 120, the conductive member 1262 and the signal output module 122 is fixed, and the conductive member is not mechanically linked with the control member 126. The 1260 and the conductive member 1262 are sometimes changed.

Referring back to FIG. 2A, when the conductive member 1260 and the conductive member 1262 are respectively coupled to the two ends of the wire circuit 1240, the output terminal 1260b of the conductive member 1260 is actually connected to the input end 1240a of the wire circuit 1240. The input end 1240a of the lead circuit 1240 can also have four conductive points to correspond to the four conductive points on the output 1260b of the conductive member 1260, respectively. Similarly, the output 1240b of the lead circuit 1240 can also have four conductive points to correspond to the four conductive points on the input 1262a of the conductive member 1262, respectively. Thereby, when the user knows that the signal transmission unit 102 can receive the left channel signal, the conduction lead circuit 1240 can be selected through the control unit 126, so that the signal output terminal 122a correctly receives the left channel signal, and the sound output device is allowed to be output. 14 can work normally.

Since the signal transmission pins of the signal output module 122 and the sound output device 14 are constant (for example, the signal output terminals 122a-122d are respectively coupled to the left speaker transmission end, the right speaker transmission end, the ground end, and the microphone transmission end), Therefore, the function of the control unit 126 is to select an appropriate wire circuit 1240, and use the wire circuit 1240 to arrange the sound source transmission connector 10 to receive the incoming earphone signal, and switch the earphone signal to the correct signal transmission path so that the signal output module 122 is on the signal output module 122. Each of the signal outputs (122a-122d) can receive the correct headphone signal for transmission to the sound output device 14. That is, when the control member 126 selects the conduction lead circuit 1240, the signal input end 120a of the signal input module 120 can be directly electrically connected to the signal output module through the conductive member 1260, the lead circuit 1240, and the conductive member 1262. 122 signal output terminal 122a. Thereby, the earphone 1 of the present embodiment can directly transmit the left channel signal carried by the signal transmission unit 102 in the sound source transmission connector 10 to the left speaker transmission end of the sound output device 14. Of course, the other earphone signals can also be transmitted to the appropriate transmission end of the sound output device 14 as described above, which is not described herein.

In a practical situation, if the electronic device is a mobile phone, and the manufacturer of the mobile phone is Apple, HTC or Samsung, the first signal transmission unit 102 of the sound source transmission connector 10 ( The first section) is designed to transmit the left channel signal; the second signal transmission unit 104 (second section) of the sound source transmission connector 10 is designed to transmit the right channel signal; the sound source transmission connector 10 The third signal transmission unit 106 (third section) is designed to transmit a ground signal; the fourth signal transmission unit 108 (fourth section) of the sound source transmission connector 10 is designed to transmit a microphone signal. At this time, since the wire circuit 1240 shown in FIG. 2A is provided with a signal transmission path between the first conductive point on the input end 1240a and the first conductive point on the output end 1240b, the sound source transmission joint 10 is The left channel signal in the first signal transmission unit 102 can be directly transmitted to the left speaker transmission end of the sound output device 14. Similarly, the conductor circuit 1240 is provided with a signal transmission path between the second conductive point on the input terminal 1240a and the second conductive point on the output terminal 1240b; a third conductive point and an output terminal on the input terminal 1240a. A signal transmission path is disposed between the third conductive points on the 1240b; and a signal transmission path is disposed between the fourth conductive point on the input end 1240a and the fourth conductive point on the output end 1240b. Each earphone signal is correctly transmitted to the sound output device 14.

However, in another practical case, if the electronic device is a Blackberry mobile phone produced by RIM, the first signal transmission unit 102 (first section) of the sound source transmission connector 10 is designed to transmit a microphone signal. The second signal transmission unit 104 (second section) of the sound source transmission connector 10 is designed to transmit the left channel signal; the third signal transmission unit 106 (third section) of the sound source transmission connector 10 is Designed to transmit the right channel signal; the fourth signal transmission unit 108 (fourth section) of the sound source transmission connector 10 is designed to transmit a ground signal. At this time, using the wire circuit 1240 illustrated in FIG. 2A, there is no way to correctly transmit each earphone signal to the sound output device 14.

Therefore, the user can directly control the control member 126, and the conductive member 1260 and the conductive member 1262 are respectively coupled to the two ends of the other lead circuit (for example, the wire circuit 1242), so that each signal output terminal on the signal output module 122 (122a~122d) can receive the correct earphone signal for transmission to the sound output device 14.

Please note that although the embodiment illustrated in FIG. 2A discloses that both the conductive member 1260 and the conductive member 1262 are movable relative to the switch 124, the control member 126 may actually control only one of the conductive member 1260 and the conductive member 1262. . For example, when the control member 126 controls only the conductive member 1260, the conductive member 1262 and the signal output module 122 can be combined so that the outputs of all the lead circuits (1240~1244) can be directly coupled to the signal output. Module 122. On the other hand, when the control member 126 controls only the conductive member 1262, the conductive member 1260 and the signal input module 120 can be combined so that the input terminals of all the lead circuits (1240~1244) can be directly coupled to the signal input. Module 120. Thereby, the embodiment can also make the wire circuits (1240~1244) in the switch 124 switch correspondingly via the moving conductive member 1260 or the conductive member 1262.

Referring to FIG. 2B, FIG. 2B is a schematic circuit diagram of an earphone coupled to another set of lead circuits according to an embodiment of the invention. The difference between FIG. 2A and FIG. 2B is that FIG. 2B illustrates that the conductive member 1260 and the conductive member 1262 are coupled to both ends of the wire circuit 1242. In detail, the wire circuit 1242 shown in FIG. 2B is provided with a signal transmission path between the first conductive point on the input end 1242a and the fourth conductive point on the output end 1242b, so that the sound source transmission joint 10 The microphone signal in the first signal transmission unit 102 can be directly transmitted to the microphone transmission end of the sound output device 14. In addition, the conductor circuit 1242 is provided with a signal transmission path between the second conductive point on the input terminal 1242a and the first conductive point on the output terminal 1242b; the third conductive point and the output terminal 1242b on the input terminal 1242a. A signal transmission path is disposed between the second conductive points; and a signal transmission path is disposed between the fourth conductive point on the input end 1242a and the third conductive point on the output end 1242b, thereby being correct Each earphone signal is transmitted to the sound output device 14.

In still another practical case, if the electronic device is a mobile phone manufactured by Nokia, the first signal transmission unit 102 (the first section) of the sound source transmission connector 10 is designed to transmit the left sound. The second signal transmission unit 104 (second section) of the sound source transmission connector 10 is designed to transmit the right channel signal; the third signal transmission unit 106 (third section) of the sound source transmission connector 10, It is designed to transmit a microphone signal; the fourth signal transmission unit 108 (fourth section) of the sound source transmission connector 10 is designed to transmit a ground signal. At this time, neither the wire circuits 1240 and 1242 shown in FIG. 2A or FIG. 2B can correctly transmit each earphone signal to the sound output device 14.

Therefore, the user can directly control the control member 126, and the conductive member 1260 and the conductive member 1262 are respectively coupled to the two ends of the other wire circuit (for example, the wire circuit 1244), so that each signal output terminal on the signal output module 122 (122a~122d) can receive the correct earphone signal for transmission to the sound output device 14.

Referring to FIG. 2C, FIG. 2C is a schematic circuit diagram of an earphone coupled to a further set of lead circuits according to an embodiment of the invention. The difference between FIG. 2A and FIG. 2C is that FIG. 2C illustrates that the conductive member 1260 and the conductive member 1262 are coupled to both ends of the wire circuit 1244. In detail, the wire circuit 1244 shown in FIG. 2C is provided with a signal transmission path between the first conductive point on the input end 1244a and the first conductive point on the output end 1244b, so that the sound source transmission connector 10 is The left channel signal in the first signal transmission unit 102 can be directly transmitted to the left speaker transmission end of the sound output device 14. In addition, the conductor circuit 1244 is provided with a signal transmission path between the second conductive point on the input terminal 1244a and the second conductive point on the output terminal 1244b; the third conductive point and the output terminal 1244b on the input terminal 1244a. A signal transmission path is disposed between the fourth conductive points; and a signal transmission path is disposed between the fourth conductive point on the input end 1244a and the third conductive point on the output end 1244b, thereby being correct Each earphone signal is transmitted to the sound output device 14.

It can be seen from the above that the difference between the wire circuit 1240 and the wire circuit 1244 shown in FIG. 2A and FIG. 2C is not large, and actually only two signal transmission paths are different. Therefore, the present invention proposes another implementation manner, so that the switching of the above three signal transmission modes can be switched by a 4-pair 2 switch (4 input signals switch two modes) and one 2 pair 2 (2 input signals switch two Mode) switch implementation.

[Another exemplary embodiment of the earphone of the present invention]

Referring to FIG. 3A, FIG. 3A is a circuit diagram of an earphone coupled to a set of lead circuits and a set of auxiliary lead circuits according to another embodiment of the present invention. The sound source transmission connector 20, the sound output device 24, the control unit 226, the signal input module 220, and the signal output module 222 of the present embodiment are the same as the previous embodiment, and are not described herein. Different from the previous embodiment, the switch 224 in the wire controller 22 of the present embodiment has only two sets of wire circuits (2240 and 2242), and a set of switches 230 and a control member 230 coupled with the switch 228 are added. The wire circuit 2240 in the switch 224 has the same terminal correspondence relationship with the wire circuit 1242 of the previous embodiment, and the wire circuit 2242 in the switch 224 has the same terminal correspondence relationship with the wire circuit 1240 of the previous embodiment.

In detail, the control member 230 mechanically interlocks the conductive member 2300 and the conductive member 2302, whereby the control member 230 can selectively control the conductive member 2300 and the conductive member 2302 to be coupled to the auxiliary lead circuit 2280 or the auxiliary lead circuit, respectively. 2282 The ends of one of the groups. Here, the auxiliary conductor circuit 2280 is provided with a signal transmission path between the first conductive point on the input terminal 2280a and the first conductive point on the output terminal 2280b; the second conductive point and output on the input terminal 2280a A signal transmission path is disposed between the second conductive dots on the end 2280b. On the other hand, the auxiliary conductor circuit 2282 is provided with a signal transmission path between the first conductive point on the input terminal 2282a and the second conductive point on the output terminal 2282b; the second conductive point on the input terminal 2282a is A signal transmission path is disposed between the first conductive points on the output terminal 2282b.

It should be noted that, for convenience of description, the wire circuit 2240 is designed the same as the wire circuit 1242, and the wire circuit 2242 is designed the same as the wire circuit 1240. However, the embodiment does not limit the wire circuit 2240 and the wire circuit. 2242 Internal actual terminal correspondence. For example, those skilled in the art should understand that if the actual terminal correspondence between the auxiliary wire circuit 2280 or the auxiliary wire circuit 2282 is interchanged at the same time, the wire circuit 2242 can of course be designed with the wire circuit 1244. the same. In addition, the same as FIG. 2A, although the embodiment illustrated in FIG. 3A discloses that both the conductive member 2260 and the conductive member 2262 are movable relative to the switch 224, the conductive member 2300 and the conductive member 2302 are both switchable. 228 moving components. However, in practice, the control member 226 may only control one of the conductive member 2260 and the conductive member 2262, and the control member 230 may control only one of the conductive member 2300 and the conductive member 2302.

Here, FIG. 3A demonstrates that the user directly controls the control member 226, and the conductive member 2260 and the conductive member 2262 are respectively coupled to the two ends of the wire circuit 2240, and the control member 230 is manipulated to couple the conductive member 2300 and the conductive member 2302 respectively. An example of connecting the two ends of the auxiliary wire circuit 2280.

Please note that in the present embodiment, only the first two conductive points of the output end 2262b of the conductive member 2262 are coupled to the signal output ends (222a-222b), and the last two conductive points of the output end 2262b of the conductive member 2262 are It is coupled to two conductive points of the input end 2300a of the conductive member 2300. In addition, the two conductive points of the output end 2300b of the conductive member 2300 are respectively coupled to the signal output ends (222c to 222d).

In a practical operation, when the user turns on the control member 226 and the control member 230 to turn on the wire circuit 2240 and the auxiliary wire circuit 2280 in the manner of FIG. 3A, the wire controller 22 can actually generate the line with FIG. 2B. The controller 12 has the same function. That is to say, the earphone 2 of FIG. 3A can be used to receive the earphone signal sent by the Blackberry mobile phone produced by RIM.

Similarly, when the user turns on the control member 226 and the control member 230 to the lead circuit 2242 and the auxiliary lead circuit 2280 in the manner of FIG. 3B, the line controller 22 can actually generate the same as the line controller 12 of FIG. 2A. Features. That is to say, the earphone 2 of FIG. 3B can be used to receive the earphone signal sent by the mobile phone produced by Apple, HTC or Samsung.

On the other hand, when the user turns on the control member 226 and the control member 230 to turn on the wire circuit 2242 and the auxiliary wire circuit 2282 in the manner of FIG. 3C, the wire controller 22 can actually generate the same as the wire controller 12 of FIG. 2C. The function. That is to say, the earphone 2 of FIG. 3C can be used to receive the earphone signal sent by the mobile phone produced by Nokia.

For the appearance and structure of the earphone, please refer to FIG. 4. FIG. 4 is a perspective view of the earphone of FIG. 3A. As shown in FIG. 4, the earphone 3 shown in FIG. 4 has a sound source transmission connector 30, a line controller 32, and a sound output device 34. The sound source transmission connector 30 is the same as the sound source transmission connector 20 in FIG. 3A and will not be described herein. Please note that the sound source transmission connector 30, the line controller 32 and the sound output device 34 are only used to illustrate the coupling relationship of the above components, and are not used to limit the sound source transmission connector 30 and the sound output device 34 to be coupled to the online control. The relative position of the device 32. For example, the sound source transmission connector 30 and the sound output device 34 can of course be interchangeably coupled to the position of the line controller 32 without affecting the function.

The line controller 32 is coupled to the sound source transmission connector 30 via the signal cable L, and the wire controller 32 has a first body portion 320 and a second body portion 322 for receiving the wire controller 22 of FIG. 3A. The component (including the switch 224 and the switch 228), and the second body portion 322 is rotatably coupled to the first body portion 320. In practice, the appearance of the first body portion 320 and the second body portion 322 are both a columnar body. For example, the columnar body may be further defined as a cylinder. That is, when the second body portion 322 is rotated relative to the first body portion 320, the second body portion 322 is actually rotated about the extension of the long axis of the first body portion 320. In addition, when the second body portion 322 is rotated, the second body portion 322 interlocks at least one of the control member 226 and the control member 230 in FIG. 3A.

Thereby, the linkage control member 226 can simultaneously couple the conductive member 2260 and the conductive member 2262 in FIG. 3A to the wire circuit 2240 or the wire circuit 2242, or the linkage control member 230 can couple the conductive member 2300 and the conductive member 2302 simultaneously. Wire circuit 2280 or auxiliary wire circuit 2282.

4, the wire controller 32 of the earphone 3 may further have a microphone 36 and a microphone switch 38. That is, the sound output device 34 may only include a speaker, and the signal output terminal of the signal output module 222 in FIG. 3A. 222d can be coupled to the microphone 36 such that the function of collecting and playing the earphone 3 is separated. In a practical manner, when the microphone switch 38 is pressed by the user, the microphone 36 of the earphone 3 starts to receive the sound. It is obvious to those skilled in the art that the functions of the microphone 36 and the microphone switch 38 can be understood. The invention will not be described in further detail here.

If the outer casing of the first body portion 320 is disassembled, reference is made to FIG. As shown in FIG. 5, when the second body portion 322 is rotated, the first linkage member 324 can be actually rotated at the same rotation speed, and the second linkage member 326a is simultaneously connected by the first linkage member 324 to be parallel to The displacement d of the major axis of the first body portion 320. Of course, the rotation angle of the second body portion 322 may have a correlation with the magnitude of the displacement d. For example, when the second body portion 322 is rotated by 90 degrees, the second linkage 326a moves toward the second body portion 322. With a displacement d, when the second body portion 322 continues to rotate 90 degrees (180 degrees total), the second linkage 326a will move a displacement d (back to the original position) in the opposite direction. Here, the present embodiment does not limit the conversion relationship between the rotation angle of the second body portion 322 and the magnitude of the displacement d, and can be set by a person having ordinary knowledge in the art.

Next, if the second linking member 326a is hidden from view, it can be seen from FIG. 6 that the second linking member 326a can actually be used to control the third linking member 328a of the switch 330a. When the switch 330a can be regarded as the switch 224 in FIG. 3A, the third link 328a can be used to link the conductive member 2260 and the conductive member 2262. In other words, the second body portion 322, the first linking member 324, the second linking member 326a and the third linking member 328a can be regarded as the control member 226 in FIG. 3A, and the user only needs to rotate the second body portion 322. The purpose of the switch 224 can be achieved. Here, the displacement d may be the actual distance that the conductive member 2260 and the conductive member 2262 are switched from the wire circuit 2240 to the wire circuit 2242. Please note that if there are three wire circuits as shown in FIG. 2A, the distance between any two wire circuits may be half the displacement d, so that the displacement 0, the displacement 0.5d and the displacement d may correspond to the three wire circuits, respectively.

However, as can be seen from FIG. 3A, the earphone of the present embodiment has not only one set of switches 330a, but also another set of similar switches 330b (which is in FIG. 7; may correspond to the switch 228 in FIG. 3A). Referring to FIG. 7, from the side view of the earphone 3, if only one set of switches 330a (and the second link 326a, the third link 328a linked to the switch 330a) and the other set of switches 330b (and When the switch 330b is linked to the second link member 326b and the third link member 328b) and the substrate 38 for setting the switch 330a and the switch 330b, the relative relationship between the switch 330a and the switch 330b can be seen.

Referring to FIG. 6 and FIG. 7 , from a practical point of view, the first linkage 324 can be appropriately designed to selectively interlock the second linkage 326a or the second linkage 326b, or simultaneously link the second linkage. Piece 326a and second linkage 326b. For example, when the user rotates the second body portion 322 by 90 degrees clockwise, the second linkage 326a can be linked through the first linkage 324, and when the user rotates the second body portion 322 counterclockwise At 90 degrees, the second linkage 326b can be interlocked through the first linkage 324. Thereby, the user can correspondingly rotate the second body portion 322 according to the manufacturer of the mobile phone, so that each earphone signal on the sound source transmission connector 30 can be correctly between the sound output device 34 (or the microphone 36) and the mobile phone. Transfer and receive.

It should be particularly noted that although the above embodiment drives the third linking member 328a to displace by rotating the second body portion 322, it is not limited thereto. For example, the second body portion 322, the first linking member 324, and the second linking member 326b may be omitted, as long as the third linking member 328a is exposed to the outer casing of the first body portion 320 and can be directly pushed by the user. In other words, when the user operates the earphone 3, the second link portion 322 may not be rotated, and the third link member 328a is directly operated in the straight line direction, and the third link member 328a is displaced by d, and the switch can also be realized. The purpose of the wire circuit in 330a. Please note that although the embodiment is exemplified by a rotating, linearly-driven operation mode, it should be apparent to those skilled in the art that the user can use the movement, sliding, pressing or other appropriate operation mode to control the wire control. Any member on the device 32 is such that the member causes the third linkage 328a to produce a displacement d, which is not limited herein.

In addition, for the manner of actuation of the third linkage 328a and the switch 330a, please refer to FIG. 8A and FIG. 8B together. FIG. 8A is a schematic structural view of a third linkage and a switch according to an embodiment of the invention, and FIG. 8B is a schematic view showing another structure of a third linkage and a switch according to an embodiment of the invention. As shown in the figure, if the switch 330a is disassembled, it can be seen that the third linkage 328a simultaneously interlocks four metal sliders (40, 42, 44, 46), and the four metal sliders (40, 42, 44, 46) can be seen as the conductive member 2260 (or the conductive member 2262) in Fig. 3A. In detail, the switch 330a can have 12 conductive pins (P1~P12), wherein the conductive pins (P1~P4) can be respectively connected to the respective signal outputs (220a~220d) of the signal input module 220 in FIG. 3A. For receiving the earphone signal from the sound source transmission connector 30. On the other hand, the conductive pins P5, P7, P9, P11 can be respectively connected to the input terminal 2240a of the wire circuit 2240 in FIG. 3A, and the conductive pins P6, P8, P10, P12 can be respectively connected to the wire circuit 2242 in FIG. 3A. Input 2242a.

Therefore, when the third linking member 328a is located at the position shown in FIG. 8A, the conductive pins P1 PP4 can be respectively coupled to the conductive pins P5, P7, and P9 through the metal sliders 40, 42, 44, and 46. P11, when the third linkage 328a is located at the position shown in FIG. 8B, the conductive pins P1~P4 can be respectively coupled to the conductive pins P6, P8 through the metal sliders 40, 42, 44, 46, P10, P12. Therefore, FIG. 8A and FIG. 8B can be an example for realizing the switching of the wire circuit 2240 and the wire circuit 2242 of the conductive member 2260 of FIG. 3A. Of course, as long as the conductive pins are connected to the appropriate input or output, the other conductive members of the present invention can be switched between the corresponding wire circuits by means similar to those of FIGS. 8A and 8B. There is no limit here.

It is worth mentioning that, since the second body portion 322 of the wire controller 32 shown in FIG. 4 can be mechanically rotated, the respective linking members are subjected to considerable stress, and thus the structure is not suitable for transmission with the sound source. The joints 30 are integrated. In particular, the sound source transmission connector 30 needs to be plugged and unplugged from time to time. If the wire controller 32 is integrated with the sound source transmission connector 30, the damage of the mechanical member is accelerated. Therefore, a signal cable L is required between the sound source transmission connector 30 and the wire controller 32 of the present invention to reduce the stress transmitted to the wire controller 32 when the sound source transmission connector 30 is inserted and removed.

In summary, the audio source transmission line and the earphone provided by the embodiment of the present invention are provided with a plurality of sets of lead circuits, and different lead circuits are different in preset correspondence relations. Thereby, the user can mechanically switch different wire circuits through the control device according to the specifications of different electronic devices, so that the earphone signal transmitted by the sound source transmission connector can be correctly received by the earphone. Therefore, the present invention can solve the problem that the transmission order of the headphone signals by different manufacturers is not necessarily the same in the case where the IC chip is not required to be used.
